I have a Canon Pixma MP150 printer and it ran out of black ink. So i decided to fill up the old cartriage with a refill and put it in the printer. However, the printer detected the same cartriage and cannot calculate the amount of ink left. I chose to "continue anyway". Then, my LED on black ink cannot stop flashing. I switched back to a proper ink cartriage(a new one not a refill) and the light is still there. How do i get the Black Ink LED to stop flashing? Am i forever screwed as they detected i tried to refill ink? I went to various websites and even the canon websites but they have nothing of this sort. How do i solve this and stop the Black Ink LED from flaswhing everytime? Thanks guys.
